Fan speed controllers

The Intelligent Fan Drive offers the possibility for energy efficient speed control of single-phase fans and three-phase fans. The control is based on a 0-10V input signal and an advanced frequency control. The fan speed can be controlled accurately according to user requirements. The specially developed and patented software gives the opportunity to achieve the highest possible energy efficiency, by using the factual and actual motor data. Especially at minimum ventilation the intelligent fan drive stands out entirely. The lower temperature in the motor results into a longer lifetime, the sturdy IP67 housing offers an optimal protection in an agressive environment.

The VLT Agro Drive enables efficient continuously variable speed control of three-phase fans. This control is based on a 0-10V input signal. The fan speed control can be adapted precisely to the demands of the user. Lower motor temperatures assure a longer lifetime, less maintenance and higher reliability. Furthermore, the energy use is strongly reduced. The VLT Agro Drive provides an optimal climate under all circumstances.

The Trilink-2t enables continuously variable speed control for single-phase fans based on a 0-10V input signal. The Trilink-2t can also be configured to control heat lamps or lighting. The maximum output current is 12.5 Amps.

The Trinc-1 enables continuously variable speed control for single phase fans 230V, 50Hz. It is integrated in the fan motor. By detecting the speed of the fan motor it can correct speed variations. As a consequence the end-user is assured that the correct Revolutions Per Minute (RPM) are maintained, independent of external wind or pressure influences.

The Trinc-2 is a module encapsulated through a low pressure injection technique. The Trinc-2 is intended for 120V, 60Hz. Comparable techniques are used in the automotive industry, where reliability under harsh conditions and compact design are key factors. As the module is encapsulated, this product has several advantages:

Protection against harsh conditions

Humidity

Mechanical stress

High reliability

Minimum dimensions for integration in existing applications

EW: Electronic Continuously Variable Manual Controllers

The EW 5 and the EW 10 are manual fan motor speed controllers for continuously variable speed control. For the EW 5 the maximum output current is 5 Amps. For the EW 10 the maximum output current is 5 Amps.
